Be it known that I, FRANK M. HILL, Jr., a citizen of the. United States, residing at Salem, in the county of Salem, State of New Jersey, have invented a new and useful Glass- Blowing Machine, of which the following is a specification.

My present invention relates to glass-blowing machines; and it consists of a novel conro struction of lifting mechanism by means of which the pressed blank is automatically removed from the press-mold.

It further consists of anovel construction coacting with the movement of the plunger i 5 to raise or lower the blow-head.

It further consists of a novel construction of lifting-rod and its adjuncts.

It further consists of other novel reatures of construction, all of which will be hereinafter fully set forth.

66 designates a pressed-glass blank.

75 and 76 designate lugs which revent im ropler movement of the neck-mold.

n t e embodiment shown in'Figs. 8 and 9,

instead of employing a single lifter-rod, as 26, 1

having a fork pivoted at itslowerend, .l employ a plurality of suclij l ods, each of said rods having an arm pivoted thereto, which engage, respectively, the hinge of the neck mold and the lugs 72 on the opposite side thereof. In this embodiment 77 designates a plurality of lifting-rods having at their lower ends a plate or stop 78 extending angularly therefrom. 79 designates a fork pivoted at 80 to the rods 77, said fork having extending therefrom the arms 81. the arms 81 engages the hinge 14, and the other of said arms engages thehws 72, which are located on the opposite side of the neckmold; v

I have deemed it unnecessary to show the One of spedt to the lifter red 26 and its adjuncts.

The operationof the device is as follows:-

Having the parts in the position seen in Fig. 1, the operator places a ball of glass of a desired. size in the press-mold, which is at this time inoperative position under the presserhead 20, or which is moved into such a position, it being understood that the table 6 is provided. with a desired number of sockets 62, with which the end of the rod 61 engages, so that when the rod is seated in one of the sockets of the table 6a press-mold and a blow-mold will be in operative position under the blow-head and the presser-head. The operator now admitsmotive fluid to the pressing mechanism 18 by actuating the Handle 49, which causes the plunger 19 and the mechanism carried thereby to move downwardly, it being understood that at this time a ball of glass is in the press mold and that the neck-mold is in operative position on the press-mold. As the plunger and its adjuncts move downwardly the arms 7 O and 71 of the fork 68 contact with the handles 15 and 16 and the hinge of the neck-meld, and, since this fork is pivoted at69 to the rod 26, as the rod 26 moves downwardly the fork will turn upwardly, as seen in Fig. 3, and will pass be.- low the arms 15;and 16 and the hinge 14, it being noted that, owing to the provision of the recess 27 in the rod 26 and the pawl 28,

carried by the plate 24, the rotation of said fork 68 will be positively prevented. The presser-head'20 engages the glass blank and forms the same in the usual manner.

As the plunger-rod 19 moves .downwardl thearm 35, carried by the block 82, wil move downwardly therewith, thus permitting the lever36-to turn on its fulcrum, said lever 36 coacting with the lever 40 by means of the pin thereon and the recess or slot in the lever 36, thus permitting the valve-pi e 43 to move downwardly, so that as tie .presser-head 20. moves mto operative position with respect to the glass blank the bottom 51 of the head 50 will engage a blowmold and close the top of the same. In; the rod 43 moves downwardlythe washer 55 will be remoyedl from its seat 56 in the valvehead and the motive fluid in the chamber 58 will be permitted to pass therefrom into the chamber 53, thence through the aperture 52;

into the blow-ri old, in which a pressed-glass blank has heretofore been placed, and this blank is now formed into the shape or conby lllc rcciprocal ng tour of the blow-mold in the usual mani'ier. When the pressing and blowing operations are completed, the lever 49 is actuated in a reverse direction, thus admitting motive fluid to the presser-head 18, and thereby raising the plunger 19 and its adjuncts. As the plunger is moved upwardly the arms 70 andslot 73 therein and the pin 39 coacting there-.

with the lever 40 will be turned on its fulcrum and the end of said lever enacting with the collar on the valve-stem will cause said valve-stem to be raised. raised the 'asher is seated in a positive manner against the seat 56 of the blow-head 50, thereby closing the admission of motive lluid to the clnnnber 53 and raising the blowhead 50 above the blmv-mold, as will be apparent from l*igs. and 7.

It is to benoted that the lifting mechanism is yieldingly supported, so that there is no shock or ar as the lil'te1-l'ork engages the handles and hinge of the neck-mold on its downward movement. It will be further apparent that 1 th the pressing and blowing mechanisms are simultaneously actuated and are when the operations of pressing amlblowing have been completed and the parts raised, as seen in Fig. l, a pressr al-glass blank will be raised above the press-mold in a position convenient to the operator lor removing said blank thcrcl'rom and placing it in a blowmold, it being seen that the blowdiead at this time is raised above the blow-mold in such a position that the blown glass therein may be readily and quickly removed and a 1:)ressedglass blank placed therein for the next blowing operation.

l l'fllll lhc above description it will be apparent that l have prodnceda novel and uselul construction of lift ing mcchimism carried plnngefaml a novel consl-ruclion in which the'blowing mechanism conlrollcd b) llldlHUVlllNlll ol' said prcssing plunger, and while l have shown in the present inslance the preferred embodiment thereol' i1 ii) be understood that it is susceptible ol' mmlilicaiion in various particulars without departing l'rom the spirit or sc pe of m invenlion o'r sacrificing any of its advantages. it will be further apparent movement of the plunger it- As the valve is controlled by a single lever, so that I invention a single lifter-rod that while in the present instance I have shown as the preferred embodiment of my having a pivoted member adapted to engage with the necl mold a plurality of such lifter-rods having apivoted member at the lower end thereof may be employed and still be within the seope of my invention. It will also be apparent that owing to the lifter-rod 26 passing freely through the plates 2], and 24 if the lifter-rod descends to such a position that the lower end thereof engages the table 6 or any obstruction thereon, the lifter-rod 26 being loosely mounted between the plates 21 and 24, the downward movement of said plates with respect to the lugs 26 willvbe permitted, as is clearly indicated in Fig. 1, and the pivoted. member will be suitably cushioned on its upward movement owing to the provisipn of the spring 33, interposed between the set-collar 32 and the plate 2], as will be evident to those skilled in this art. It will be further apparent that while I have plates it is to be understood that these are simply stops carried by the lifter-rods in order that the pivoted fork or arms on their upward movel'nent will be maintained in a suitable horizontal position.
